Pulgadas: Fractions Calculator

Pay once and use it forever. No subscription, no unlocks, every feature included. The calculator for cuts. Pulgadas adds, subtracts, multiplies and divides tape-measure fractions exactly, rounds to the mark on your tape, and shows you where the result lands. Built for cabinetmakers, carpenters, furniture makers and anyone who measures in sixteenths. ENTER NUMBERS THE WAY YOU READ A TAPE Three keypads: whole inches on the left, numerator and denominator on the right. Type 1, then 3 on the fraction pad, and you have 1 3/16 at sixteenth precision. No converting to decimals, no hunting for a fraction key. EXACT MATH, NO DRIFT Every value is kept as an exact fraction. Nothing is rounded until it reaches the display, so a chain of cuts adds up to the same total you started with. 96 inches split seven ways and multiplied back is 96 inches, not 95 13/16. ROUND TO YOUR TAPE Pick 1/2, 1/4, 1/8, 1/16, 1/32 or 1/64. Choose Down for parts that must fit, Up for parts that must cover, or Nearest. Whenever rounding changed the answer, the exact value is shown underneath so you know what you gave up. SEE IT ON THE TAPE Tap the tape button and the display becomes two inches of a dual-reading tape centered on your result, with a red mark where the cut lands. Inches on top, millimeters below. It follows the number as you type. EVERY STEP EXPLAINED Open the steps sheet to see how the answer was reached: common denominators, the operation, simplifying, back to a mixed number, and the rounding to your tape. Good for checking your own math, and for teaching an apprentice. INCHES, FEET AND INCHES, OR MILLIMETERS Switch units at any time. In millimeter mode the keypad becomes a decimal pad and typed millimeters convert exactly to inches. The other units are always shown under the result, so 32 mm hardware and 23/32 plywood live in the same calculation.
